Longmont Auto Repair

Thank you guys for everything, you are always nice and actually listen to my needs. Very honest, reliable and with flawless execution and on-time delivery I will always come here. I think I found my go to mechanics since moving to colorado from Utah. Thanks!

Great communication and awesome service; will be back!

Answer my questions the best they could and lent me the tools to fix my truck

Brilliant, Honest, and Timely. Had taken my LML Duramax to another shop, for it to sit for a month before told that, " I melted a piston" and "needed a new engine." Called Cory, explained the situation, and was immediately impressed with his communication and knowledge. Automotive Authorities identified the issue, gave me daily updates, and had my truck running better than ever, in barely a week. I am so grateful to Cory and his people for literally saving me 20,000 dollars on an unnecessary replacement for an 8 year old motor. AA will forever have my family's business and gratitude.

I have been taking my cars to Automotive Authorities for several years. Cory and his employees are honest, professional and friendly. I trust them with all of my car's needs.

YOU GUYS ARE THE BEST

Been going to these guys for a while. Always honest, after looking for years for someone who wont B.S. thier customers for more money. I always tell people about them. Best mechanic around!

I have used AA for several years now, on a number of different cars. I recently needed them to evaluate a car that my nephew wanted to purchase. They were able to squeeze me in earlier than I expected, due to a cancellation, and their evaluation found several issues resulting in our taking a pass of buying the car. Thanks Cory, and your team.
